DVB Demod/Modulator

Description

The iD135 has been designed for Satellite Broadband applications, leveraging Ka-band and multi-spot beam technology carried by the latest high-throughput satellites (HTSs).

The iD135 has been designed to enable single-carrier usage of HTS transponders. The device implements two high-symbol-rate (HSR) demodulators compliant with Annex M of the DVB-S2/S2X specification EN 302 307, and provides full HW support for network clock recovery (NCR) in order to enable external return-channel modulators.

The iD135 may be used in standard broadcast environments as an 8-channel DVB-S2/S2X receiver enabling multi-channel distribution and/or fast channel change scenarios.

Features

Two high-symbol-rate (HSR) demodulators:

Maximum baud rate 500 Msymbol/s

Up to two slices each

DVB-S2/S2X and Annex M compliant

Up to 8 multi-standard demodulators:

S/S2/S2X/DTV

Integrated full-band tuners and ADCs

High-speed digital multiplexer to connect any tuner to any demodulator

DVB T2/T/S2/S and C Demodulator IP

Description

DVB-T/T2/C/S2 IP is a highly optimized multi standard DVB-T/T2/C/S/S2 Decoder solution designed for next generation satellite, cable and terrestrial digital television reception.

DVB T/C Demodulator SoC White Box IP

Description

The V0367 inherits the functionality of the industry-leading enhanced V0362 terrestrial and V0297E cable demodulators in one single advanced combo receiver.
The V0367 COFDM section of the receiver is fully compliant with the DVB-T standard framing structure, channel coding and modulation. The symbol, timing and carrier recovery loops are completely digital and tailored to comply with state-of-the-art RF down-converting tuner devices.
The V0367 DVB-C section is a complete QAM (quadrature amplitude modulation) demodulation and FEC (forward error correction) solution that performs IF-to-transport stream block processing of QAM signals.
The demodulator provides error-corrected MPEG transport-stream outputs which can be routed to the transport sub-system.

Features

Combined DVB-T/-C receiver

DVB-T demodulation

DVB-C demodulation

I²C serial bus interface

Compatible with low- to high-IF tuners

Flexible clock management

ADC for RF signal strength indicator

Flexible and DVB-CI compliant TS output

Ultra-compact TQFP64 package

Benefits

This highly integrated SoC helps to reduce board area and manufacturing cost, allowing low cost and small size STBs to be designed for either DVB-C or DVB-T networks.
